It is preferable that at least two points on the outer periphery of the rotation preventing portion are formed so as to be able to simultaneously contact the inner surface of the insertion hole when rotated as the rotation center. With this configuration, a gap is formed between the rotation prevention portion and the inner surface of the insertion hole, so that the workability of inserting the slide bush into the insertion hole can be improved. In addition, the rotation of the slide bush can be reliably prevented by forming at least two points on the outer periphery of the rotation preventing portion so as to be able to simultaneously contact the inner surface of the insertion hole.

  • a rotation blocking part 10 for blocking the rotation of the slide bush 1 is provided at the other end 2a of the cylindrical part 2 (on the side of the upper part of the cylinder).
  • the rotation preventing portion 10 is also configured with a force obtained by forming the other end 2a of the cylindrical portion 2 of the slide bush 1 in an elliptical shape.
  • the rotation prevention unit 10 is inserted into the insertion hole 6 and then swung.
  • the insertion hole 6 is composed of a substantially circular hole 11 and an elliptical hole 12 communicating with the hole 11. When the cylindrical portion 2 of the slide bush 1 is inserted into the insertion hole 6, rotation is prevented.

  • a gap is formed between the rotation preventing portion 10 and the hole 12.
  • the rotation preventing portion 10 is provided at the other end 2a of the cylindrical portion 2 of the slide bush 1, so that the joint rotation of the slide bush 1 is reliably prevented. That is, the rotation prevention unit 10 has a gap formed between the outer periphery of the rotation prevention unit 10 and the inner surface of the hole 12. From this state, when the rotation prevention part 10 rotates around the center M of the hole 12, two points on the outer periphery of the rotation prevention part 10, that is, both ends 10a and 10b of the major axis of the rotation prevention part 10 are simultaneously Since it abuts against the inner surface, the rotation of the slide bush 1 can be reliably prevented.
  • the assembly workability does not deteriorate with the formation of the rotation prevention part 10.

Therefore, it is possible to eliminate the possibility of deformation of the rotation preventing portion 10 and thus the slide bush 1.
  • the rotation preventing portion 10 and the hole 12 forming a part of the insertion hole 6 are formed in an elliptical shape, but may be formed in a triangular shape as shown in FIG. 3, for example. Yes.
  • the rotation prevention unit 10 rotates around the center M of the hole 12 from a state where a gap is formed between the outer periphery of the rotation prevention unit 10 and the inner surface of the hole 12, each peak Since the three points 13, 14, and 15 are simultaneously brought into contact with the inner surface of the hole 12, it is possible to more reliably prevent the slide bushes from co-rotating.
  • the rotation preventing portion 10 and the hole 12 forming a part of the insertion hole 6 may be formed in a quadrangular shape as shown in FIG. In this case, when the rotation prevention part 10 rotates around the center M of the hole 12, the four apex angles 16, 17, 18, 19 are simultaneously brought into contact with the inner surface of the hole 12. The joint around the slide bush can be prevented more reliably.
